What is usually identified as S. subulata is a popular aquarium plant which is currently cultivated by most major nurseries. It is commonly available in well-stocked stores listed as 'Dwarf Sagittaria'.
S. subulata as applied to the plant commonly grown in the hobby is suspect, and most likely applies to a related species of swampy habitats in the Southern United States and perhaps farther south, as opposed to the tiny plant of fresh and brackish tidal mudflats in the Northeastern United States. In the recent past, the concept of S. subulata as a species was much broader and likely included both plants. The true identity and current name of the commonly cultivated species remains to be determined.
